PMIC – Supervisors are integrated circuits (ICs) that exist in an embedded system and play an essential role in managing and maintaining proper system operations. They are used to provide system-level guidance and protection to the embedded device and protect it from a wide range of possible errors and undesired errors scenarios. One such example is the TL7705ACPSR, a low power supervisor IC that can monitor two independent power supplies and provide protection against brownout and over voltage.

The TL7705ACPSR is a PMIC – Supervisor device specifically designed for low power, low voltage applications such as PDAs, cellphones and battery-operated devices. It features two voltage ORs that allow the system to detect two independent power supplies, enabling an overall high level of system monitoring and protection from overvoltage conditions, as well as brownouts. The device also offers over-voltage protection and auto recovery functions.

The TL7705ACPSR has an integrated circuit that is both tiny and highly efficient, consuming only 0.5% of the power consumed by a traditional supervisor IC. By reducing power consumption, the TL7705ACPSR is capable of increasing battery life and reducing the need for size and weight optimizations with the system.

TL7705ACPSR is quite easy to use in a variety of applications and offers several configuration options which allow the user to customize the functionality of the device. It is equipped with a number of pins which allow it to be connected to different digital parts and peripherals, such as interrupt pins, LED outputs, and optional input/output pulldowns.

In terms of its working principle, the TL7705ACPSR’s integrated circuit monitors the voltage levels of its two independent power supplies and provides a reset signal when either supply goes out of range. The integrated circuit then drives the reset signal to the reset pin, forcing the system to restart itself in order to eliminate any undesired feedback from the overvoltage conditions or brownouts.

In summary, the TL7705ACPSR is a highly efficient, low power supervisor IC that is both versatile and easy to use. It monitors two separate power supplies and provides protection against overvoltage conditions and brownouts, as well as offering a number of other configuration options to customize the device’s functionality.
